It’s no exaggeration to say that polio shaped modern medicine. Before a vaccine was available, polio outbreaks left thousands of people paralyzed, with some unable to breathe. But, in 1928, the development of the iron lung meant that, for the first time, humans could rely on a machine to stay alive. In this episode, we trace the rise of polio in the early 20th century, the science behind the virus, and the race to save lives. From early resuscitation experiments to the unexpected inspiration behind the iron lung, we uncover the innovation, ethical dilemmas, and human stories that defined this era, hearing from two people whose early childhoods and families were dramatically shaped by the disease.
